Location of events projected on the Sun surface, with the latitude as a function of longitude in the Stonyhurst heliographic coordinate system. The circles locate the mean latitude and longitude for a given event, and are coloured in red for limb and quasi-limb event, i.e. with a longitude ∈[45° ,135° ] ∪ [ − 45° , − 135° ], and in blue for the others. Black dashed lines represent delimitation between far side (two opposite side of the figure) and on disc (the middle of the figure) events.
